Critic of Wikipedia

One of my sons recently asked me if we were really Jewish and I'd been holding out on him all these years. When I raised a surprised eyebrow, he drew my attention to the entry on me in Wikipedia (Can you trust Wikipedia?, October 24). Amid otherwise accurate, if selective facts, it asserts that I am a Jewish writer who is currently music critic of the Sunday Times. Some of my best friends may be Jewish, but I am not, and I am music critic of the Observer.

Chris Newrat claims that William Blake's "satanic mills" were the universities of Oxford and Cambridge (Letters, October 27). It has also been said that they were the hypocritical churches of the established religions. But he is wrong to say Blake predated the industrial revolution. There were plenty of dark satanic industrial mills about in Blake's day. The first water-driven mill for spinning, the silk mill in Derby, was opened in 1704, 50 years before Blake was born.

If 35% of all households will consist of one person by 2021 (Young women lead move to solo living, October 27), can we hope that just one of the political parties will recognise the existence of voters who are something other than members of a "hard-working family"? Pat Oddy Yarm, Teesside
